Aniline

Vedclass · Answer

(A) The dye test is a characteristic reaction of primary aromatic amines. When primary aromatic amines like $Aniline$ $(C_6H_5NH_2)$ are treated with nitrous acid $(HNO_2)$ at $0-5 \ ^{\circ}C$,they form a diazonium salt. This diazonium salt then undergoes a coupling reaction with phenols or other aromatic amines to form azo dyes,which are colored compounds. Since $Aniline$ is a primary aromatic amine,it gives the dye test,whereas aliphatic amines like $Methylamine$ and $Ethylamine$ do not form stable diazonium salts at these temperatures,and $Diphenylamine$ is a secondary amine.
